4.11-stable review patch. If anyone has any objections, please let me know.
------------------ From: Kai Chen <[email protected]> commit 4c4c565513cca1c53a12956640b5915727431631 upstream. The decoupled MMIO feature doesn't work as intended by HW team. Enabling it with forcewake will only make debugging efforts more difficult, so let's disable it.
